DGML, or the Directed Graph Markup Language, is an XML-based format used to describe directed graphs. Directed graphs consist of vertices (or nodes) connected by edges that have a direction, indicating a one-way relationship between the nodes. DGML is particularly useful for visualizing graphs in applications such as software development, data analysis, network modeling, and more. DGML allows users to represent structures like dependencies, relationships, and hierarchies in a clear and standardized way.
DOT is a plain text graph description language primarily used for representing directed and undirected graphs. It is part of the Graphviz software suite, which is an open-source graph visualization tool. DOT allows users to specify the nodes and edges of a graph in a simple syntax, making it easy to define graph structures programmatically.
GraphML is an XML-based file format designed for representing graphs, which can be directed or undirected, and is suitable for use in a wide range of graph-related applications, including network analysis, social network analysis, and data visualization. Key features of GraphML include: 1. **Structure**: GraphML is structured in a way that allows for the representation of nodes, edges, and their associated attributes.
Graph Modelling Language (GML) is a descriptive language used for representing graphs in a structured format. It provides a way to specify the properties of nodes (vertices) and edges (connections) in a graph. GML is particularly useful for exchanging graph data between different applications and tools, as it offers a standardized way to describe various attributes and relationships. ### Key Features of GML: 1. **Hierarchical Structure**: GML uses a simple, hierarchical structure that can represent complex graphs.
PGF/TikZ is a powerful package used in LaTeX for creating graphics programmatically. - **PGF**: Stands for "Portable Graphics Format." It serves as a backend for producing graphics and includes functionality for creating figures and diagrams in a way that is highly customizable. PGF is essentially a lower-level interface. - **TikZ**: Stands for "TikZ ist kein Zeichenprogramm," which translates to "TikZ is not a drawing program.
Trivial Graph Format (TGF) is a simple text-based format used to represent graphs. It is designed to be easy to read and write, making it a suitable choice for basic graph data representation, particularly in contexts where simplicity is more important than complexity or efficiency. In TGF, a graph is represented using two sections: 1. **Node Section**: This section lists the nodes (or vertices) of the graph.
Bipartite dimension is a concept from graph theory, specifically in the study of dimension in combinatorial structures. In simple terms, a graph is considered bipartite if its vertex set can be divided into two disjoint subsets such that no two graph vertices within the same subset are adjacent. The **bipartite dimension** of a graph is defined as the minimum number of dimensions needed to represent the graph in a way that respects the bipartite structure.
The concept of a "bondage number" typically arises in the context of graph theory. Specifically, the bondage number of a graph is defined as the minimum number of edges that must be removed from the graph in order to make it impossible to maintain a dominating set—that is, a set of vertices such that every vertex in the graph is either in the dominating set or is adjacent to a vertex in the dominating set—of a certain size.
The Cheeger constant, also known as the Cheeger function or Cheeger number, is a concept from graph theory and geometric analysis that provides a measure of how "well-connected" a graph or a manifold is. In the context of a graph, the Cheeger constant is used to characterize the minimum cut that can be made to partition the graph into two disjoint sets.
Closeness centrality is a measure used in network analysis to determine how central or important a particular node (vertex) is within a graph. The idea behind closeness centrality is that nodes that are closer to all other nodes in the network are more central than those that are farther away. This metric is particularly useful for understanding the efficiency of spreading information or resources through the network.
Pinned article: ourbigbook/introduction-to-the-ourbigbook-project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
